Respuesta :
-p(51 + z) = dz + 84
-51p - zp = dz + 84
-84 - 51p = dz + zp
-84 - 51p = z(d + p)
z = (-84 - 51p)/(d + p)
Unless you know the values of d and p, this is as far as you can go.

you would want to get to the negative p and then look at the inside of the parantheseis write the expression then add them
